Trapezoidal Profile
A straight-lined panel with a clear trapezoidal corrugation. Most often used for outbuildings, garages, warehouses, and simple-architecture single-family homes. A more economical option with lower material use per square meter.

Metal Roof Installation in Riga
Installation of profiled steel sheeting, trapezoidal profile, and tile-effect profile roof coverings, with precise battening, correctly built details, and a written warranty - a durable, cost-effective solution for a single-family home or outbuilding.
Who it's for
The Most Popular Covering for Riga and Pierīga Homes
A metal roof covering is the most in-demand solution for both new builds and existing house roofs - it combines a reasonable price, low weight, and a long service life without demanding a complex structure. It suits anyone who wants a practical, durable solution without overpaying for material.
Profiled steel sheeting works for simple gable-roof geometry as well as more complex roof shapes with multiple ridge details, entrance canopies, and eaves solutions. The material's low weight lets it be installed on a lighter rafter structure and battens than heavier coverings such as roof tiles.
Why choose a metal roof
A Durable Covering Without Unnecessary Overpaying
A metal roof solves several practical problems at once - weight, cost, and installation speed.
Low Weight on the Structure
Adds no extra load to the rafters - suitable even for lighter new-build structures.
Long Service Life
A quality coating and correct installation deliver decades of service.
Faster Installation
Large-format panels let us cover the roof faster than with small-unit materials.
Scope of work
What's Included in Metal Roof Installation
Building the Battens
Batten spacing to match the chosen profile's requirements and the roof pitch.
Anti-Condensation Membrane
A membrane under the covering that prevents condensation building up on the underside of the sheeting.
Covering Panel Installation
Fixing the profiled sheets with the correct overlap and fastener spacing.
Ridge Element Installation
Ridge cap sheets that close off the top detail and ensure ventilation.
Verge and Eaves Flashing
Side and bottom edge finishing that protects the structure from wind and water ingress.
Snow Guard Installation
Additional snow guards installed above entrances and driveways where needed.
System layers
The Structure Beneath the Metal Covering
A metal roof's longevity is determined not by the sheeting itself, but by the layers beneath it.
1. Rafter Structure
The load-bearing timber structure, checked or built to match the roof pitch and planned load.
2. Breather Membrane
A wind and moisture barrier that lets vapor escape the structure while keeping water out.
3. Ventilation Gap
The air gap between membrane and battens that prevents condensation building up under the sheeting.
4. Metal Roof Battens
Wider or narrower spacing depending on profile type - batten spacing matched to the chosen covering.
5. Anti-Condensation Membrane
An additional protective layer directly under the sheet panels that absorbs and channels away condensation.
6. Profiled Steel Covering
Panel installation with correct overlap, screw spacing, and sealing washers at every fixing point.
Material variants
Profiled Steel or Tile-Effect Profile
The two most commonly chosen metal roof profile types - they differ in appearance and use.
Tile-Effect Profile
A panel with a wavy, tile-like surface relief. Blends visually into more traditional developments and resembles a classic tiled roof, while keeping the advantages of metal - lower weight and faster installation than real tiles.
Critical details
The Details That Determine a Roof's Durability
A metal roof's durability is determined not by the panel, but by how the details are executed. Ridge elements need to be installed with the correct overlap and ventilation gap so the roof "breathes" and condensation doesn't form beneath the sheets.
Verge flashing connections need to be built so wind can't get under the covering at the side edges, and eaves flashing needs to be fixed with the correct slope so water is channeled straight into the gutters rather than dripping behind them. In areas with heavier snow buildup, especially above entrances, we install snow guards that prevent an uncontrolled slide of snow off the metal covering.
Process
How Metal Roof Installation Happens
1
Site Visit & Measurements
Assessing the roof structure and pitch, choosing the profile.
2
Quote & Material Order
A detailed calculation and ordering sheet panels to precise measurements.
3
Building the Battens
Membrane, ventilation gap, and battens matched to the profile's requirements.
4
Panel Installation
Fixing the sheet panels with correct overlap and screw spacing.
5
Detail Finishing
Ridge, verge, eaves flashing, and snow guard installation.
6
Handover
Quality control, site clean-up, warranty documents.
Quality control
How We Check Completed Work
At the end of each installation stage, we check screw fastening spacing, overlap tightness, and detail waterproofing. We photograph critical points - the ridge, verge, and eaves connections - before and after finishing, so the process stays verifiable even after the work is done.
Before handover we check that every fixing point is tight, sealing washers aren't damaged, and the ventilation gap isn't blocked. On projects with multiple roof slopes or more complex details, we carry out an additional visual walkthrough with the client before signing off.
Price
What Affects the Cost of Metal Roof Installation
We prepare an exact quote after the site assessment - here are the main factors that affect price.
Roof Area and Geometry
Total covering area and number of details - multiple slopes and ridges increase the amount of work.
Profile and Coating Choice
Trapezoidal or tile-effect profile, coating type, and thickness affect material cost.
Existing Structure
Whether new battens need to be built or the existing ones can be reused affects the amount of work.
Additional Details
Snow guards, additional ventilation elements, and more complex verge flashing.
Duration
Metal roof installation on an average single-family home usually takes 4-8 working days depending on roof area and detail complexity.
Warranty
A written warranty for the installation work and the manufacturer's warranty for the covering. Terms are described on our warranty page.

FAQ
Frequently Asked Questions About Metal Roofs
A quality profiled steel sheet with a proper polymer coating and correct installation typically lasts 30-50 years. Lifespan largely depends on the coating type, batten quality, and correct ventilation beneath the covering.
If the roof has full insulation, a breather membrane, and correctly built battens, rain noise is practically inaudible indoors. Noise problems mainly arise where there isn't enough insulation beneath the sheeting or the structure was built imprecisely.
A trapezoidal profile is a straight-lined panel with sharp, geometric ridges - more economical and commonly used for outbuildings and simple-architecture single-family homes. A tile-effect profile imitates the wavy surface of classic roof tiles and blends visually into more traditional developments, while keeping the strength and lower weight of a metal covering.
Yes, if the rafter structure and battens are in technically sound condition. In that case it's a roof covering replacement rather than a full installation - during the site assessment we evaluate whether the existing structure suits the new covering.
